Reticulated acanthoma with sebaceous differentiation (RASD) is a rare, benign cutaneous tumor with peculiar histopathologic characteristics [1]. RASD had been described under various synonyms such as superficial epithelioma with sebaceous differentiation, sebocrine adenoma, poroma with sebaceous differentiation, and seborrheic keratosis with sebaceous differentiation [2]. Clinical differential ...

Solitary fibrous tumors are submesothelial mesenchymal fibroblastic tumors that typically occur in relation to parietal or visceral pleura. However, the tumor also occurs in extrapleural sites, including the peritoneum, mediastinum, orbit, and oral cavity. With the advent of immunohistochemical testing, certain tumors may be more readily identifiable; however, the diagnosis often must be reache...

Solitary fibrous tumors (SFTs) may occur at any site in the body. SFTs can only be conclusively diagnosed based on histopathologic and immunohistochemical characteristics of the tumor. The presence of SFTs in the abdomen and pelvis is extremely rare. To our knowledge no cases of urethral solitary fibrous tumor in the literature have been reported so far. We present a case of a solitary fibrous ...

Primary adenocarcinoma of the urinary bladder is a rare neoplasm sometimes causing diagnostic challenge because it can be indistinguishable morphologically from adenocarcinoma secondarily involving the bladder by metastasis or direct extension. Identifying the primary origin of the tumor is important in staging, determining appropriate therapy and assessing prognosis. We report herein a case of...

Methods Over a 7 year period, 161 patients were referred for CMR for evaluation of a known or suspected cardiac mass. A retrospective chart review of these 161 patients revealed that 42 patients (26%) had subsequent biopsyproven diagnosis of a cardiac mass. CMR characteristics of biopsy proven cardiac masses, including contrast enhancement on first pass and delayed images, signal intensity on T...

Ameloblastoma is a true benign odontogenic neoplasm with many classical histological variants, common being follicular and plexiform types. Hemangiomatous amelobalstoma is a very rare variant that shows unique histopathologic characteristics varying from conventional ameloblastoma. We present a rare variant of ameloblastoma in a 35-year-old female patient with a swelling over left mandibular re...
